This chapter dealt with some of the technical problems that were encountered while working with the models throughout this book. While processing and deploying the models, the amount of data and the way in which the data is processed directly affects the time to deploy a solution. It also affects the accuracy of the models; we might also miss out on valid models if we do not tune the algorithm with the help of certain parameters. Therefore, we visited the models discussed in this book. We also discussed which parameters can be altered to improve the processing performance, ensuring the validity of the models. Lastly, we discussed the problem that we encountered during the deployment of the model and took corrective actions.
